Roman Trivia (Posted on 2009-05-17) Difficulty: 2 of 5
Take all the Roman numbers (using the modern standard subtractive notation in which IV = 4, IX = 9, XL = 40, XLIX = 49, XC = 90, etc.) from I to M (1 to 1000)...

1. Which number has the most Roman letters?

2. If you group them by the number of Roman letters, which group has the most members?

3. How many numbers start with C?

4. There is something interesting about the groupings in #2. What is it?

I have no idea how that got the way it did.

I had started to enter it using the Chrome browser, but decided IE is usually better for entering comments, and so copied and pasted from the Chrome text box to the IE text box, and then copied and pasted the source code from a text editor into the IE text box and then submitted the comment.

The white boxes surprised me; I didn't do anything to get that formatting.
